First off I have to say a massive thanks to @My Old Landy for spoon feeding me through the VFD & 3ph motor process, I would still be googling about if it were not for his excellent advice and patience - better distance learning than the OU!
I got this Pollard from @BarrieJ a fair while back and have used it a lot, but it's fast speeds have always been a limitation.
Upgraded the 8mm chuck to a 13mm on a JT2, then it really was time to vary slower speeds.
On advice, got a TEC 3ph motor and a Parker AC10 inverter - then the fun..
I made a new 10mm thick backplate, I knocked it up in MDF first and I'm glad I did, the hole spacing had to be pretty much cock on to get the centre and height right, the original mount bolt spacing meant I had to offset the plate for the motor to mount central, took a fair bit of measuring..
The original plan was to replace the flat belt pulleys with V groove pulleys, but that would have meant some serious modification to the driven spindle setup so decided to keep the original flat belt and pulleys, which meant only the original rear drive pulley would need modifying to accept the motor drive spindle. My toy lathe would no be able to bore it out to required 28mm so a very kindly chap did it for me and all I had to do was fettle the bore a bit and tap for dog point grub going into the motor spindle
All bolted up and working a treat with the VFD.
VFD temporarily mounted on the drill body but once I have a bit of a shake up the Pollard will be positioned where that racking is behind and the VFD will go in an enclosure on the wall.
I've mounted a tacho and a remote is on the cards with lots more functionality.
Again a massive thanks to @My Old Landy for help and config on the VFD, couldn't have done it without you mate - Get well soon
